One-time password generation apparatus and method using virtual input means

Abstract

One-time password (OTP) generation apparatus and method using virtual input means are provided. Reference information generated by a reference information generation unit is compared with identification information. When the reference information is identical to the identification information, a value corresponding to indication information is generated as an OTP.

1 . A one-time password (OTP) generation apparatus ( 10 ) for user authentication, comprising:
 a reference information generation unit ( 110 ) configured to generate reference information; and   an OTP generation unit ( 130 ) configured to generate a value corresponding to indication information as an OTP when the reference information and identification information are identical to each other.   
     
     
         2 . The OTP generation apparatus of  claim 1 , wherein the OTP generation unit ( 130 ) generates an OTP with reference to an initial value. 
     
     
         3 . The OTP generation apparatus of  claim 2 , wherein the initial value is a password that is previously determined for user authentication. 
     
     
         4 . The OTP generation apparatus of  claim 2 , wherein when the reference information and the identification information are different from each other, the OTP generation unit ( 130 ) sets the initial value as an OTP value. 
     
     
         5 . The OTP generation apparatus of  claim 1 , wherein the reference information generation unit ( 110 ) generates the reference information by a user's designation. 
     
     
         6 . The OTP generation apparatus of  claim 5 , wherein the reference information is generated from a position, order or other terminal designated by a user. 
     
     
         7 . The OTP generation apparatus of  claim 1 , wherein the reference information generation unit ( 110 ) includes a table generation unit ( 111 ) configured to generate a table of which columns is capable of being designated by a user, and information corresponding to the column of the table designated by the user is generated as the reference information. 
     
     
         8 . The OTP generation apparatus of  claim 1 , wherein the reference information and the identification information are same type. 
     
     
         9 . The OTP generation apparatus of  claim 1 , wherein the reference information and the identification information are information of one or more selected from the group consisting of a color, a sound, a symbol, an image, and a vibration. 
     
     
         10 . The OTP generation apparatus of  claim 1 , wherein the indication information is direction indication information that indicates a specific direction. 
     
     
         11 . The OTP generation apparatus of  claim 10 , wherein when the reference information and the identification information are identical to each other, an initial value is changed to a value of a direction corresponding to the direction indication information and is then generated as the OTP. 
     
     
         12 . The OTP generation apparatus of  claim 1 , wherein when the OTP generation apparatus ( 10 ) is tilted or shaken the value corresponding to the indication information is a tilt or shaking value that is generated by a tilt and shaking detection unit ( 150 ). 
     
     
         13 . The OTP generation apparatus of  claim 1 , further comprising a virtual input means generation unit ( 170 ) configured to generate virtual input means, wherein the generated OTP is input through the virtual input means. 
     
     
         14 . The OTP generation apparatus of  claim 13 , wherein the virtual input means is a QWERTY keyboard or a virtual key pad. 
     
     
         15 . The OTP generation apparatus of  claim 13 , wherein the value corresponding to the indication information is a pattern value, a repetitive input value of a specific value, or a continuous input value of a specific value, each of which is input through the virtual input means. 
     
     
         16 . The OTP generation apparatus of  claim 10 , wherein the value corresponding to the indication information is a previously determined value. 
     
     
         17 . The OTP generation apparatus of  claim 1 , wherein the OTP generation apparatus ( 10 ) is a server or user terminal ( 100 ). 
     
     
         18 . The OTP generation apparatus of  claim 1 , wherein the reference information and the identification information are changed at every request for user authentication. 
     
     
         19 . The OTP generation apparatus of  claim 1 , wherein when incorrect OTP is input three or more times, the reference information, the indication information, and the identification information are changed. 
     
     
         20 . An OTP generation method for user authentication, comprising:
 generating reference information by a reference information generation unit ( 110 ) (S 10 );   determining whether the reference information and identification information are identical to each other (S 20 ); and   generating, by an OTP generation unit ( 130 ), a value corresponding to indication information as an OTP when the reference information and identification information are identical to each other (S 30 ).   
     
     
         21 . The OTP generation apparatus of  claim 12 , wherein the value corresponding to the indication information is a previously determined value. 
     
     
         22 . The OTP generation apparatus of  claim 15 , wherein the value corresponding to the indication information is a previously determined value.
